New study looks at the demographics of those who stormed the U.S. Capitol

9. I sincerely hope this research isn't as flawed as it sounds?

From what they’ve stated, it appears they have looked at a demographic that has already been through several filters.
They looked at a group of people who could - at relatively short notice, book and pay for hotels in DC They have studied a group that did not have to be at work - and a group for whom childcare wasn’t a problem.

Which means they are likely an older group, without kids who are unable to fend for themselves for a weekend. It makes it more likely that they are white collar, because people who work in offices are more able to work remotely - preserving income and making working remotely more possible.
And if you are white collar and working in an office, you are more likely to live in an urban rather than rural area, which is therefore more likely to be a place where Biden won.

For every middle aged estate agent or bank employer with teenage children who could stay home alone, there are probably thousands of people working blue collar jobs, with nothing in the bank and kids who need minding.
Perhaps one other figure they should consider is that the 800 people who showed up, are the number of people who could make the trip, out of the 70 million who voted for Trump. 1 out of every 1,250.
